So what happens when you hit the limit of 8 WoW accounts on your BNet? You're screwed and can't add anymore WoW accounts? Within the last 6 weeks both Vecter and HPAVC have indeed broken accounts/characters off of one BNet onto another by calling Blizzard directly and having it done without a fee. Unless Blizzard's policy has changed in the recent weeks, I don't see why you guys are not able to do this. Are you wording your questions incorrectly? I will attempt to call them myself [if I wake up early enough tomorrow] and talk to them directly to see what they say about this.

To add: I have also broken up my BNet accounts but this was back in January so I felt my situation was exempt this late in the year.
